Chapter 12: Hydrogen: The First Atom

The ontic sequence is complete: vacuum → neutron β^- proton + electron + antineutrino (Chapters –). But the sequence does not end with three separate particles. The proton and electron, born from the same neutron, remain linked on a shared T² torus. Their co-rotor configuration is hydrogen—the first atom, the simplest composite defect bundle, and the gateway to all of chemistry. This chapter derives hydrogen’s ground state, the Bohr radius, and the binding energy from the τ³ framework, completing Part I and setting the stage for the Complexity Arc (Parts II–VIII).
